Description

Cashmere short fibre yarn and preparation method thereof
Technical field
The present invention relates to a kind of main fibre length at cashmere short fibre yarn of 20mm~25mm scope and preparation method thereof.The invention particularly relates to a kind of main fibre length at pure cashmere short fibre yarn of 20mm~25mm scope and preparation method thereof.
Background technology
Known in this field, textile fiber must have certain length, so that in when spinning, can make that fiber forms certain entanglement, distribution and cohesive force each other in the yarn, has the fabric yarn of performances such as certain brute force, flexibility, elasticity, elongation with formation.Therefore, fibre length about 20mm or length in the staple fibre nonwoven weaving yarns performance of 20mm~25mm scope, can't be used for weaving of garment fabric etc. usually.Though, staple fibre with 20mm left and right sides length is also arranged once in a while in conjunction with other long fiber, be used for the manufacturing of nonwoven fabric etc., to make full use of staple fibre, reduce product cost.But its intensity is very low, can't be effective to as the practical occasion of need such as clothes than high-tenacity.Under normal conditions, fibre length about 20mm and/or the user of the staple fibre of 20~25mm scope few.
As everyone knows, cashmere fiber, promptly usually said cashmere fibres have the title of " soft gold " in textile industry.Because of cashmere fibres comes compared with all other fibrous raw materials, its fiber number is more very thin; Warmth retention property is better; Feel is more sliding, refreshing, glutinous; Saturating wet, permeability is excellent, is a kind of " superfine product " textile raw material always.Yet the annual production quantity in the goat cashmere whole world is very limited, and the price of its fiber and finished product fabric thereof is surprising.
In addition, because cashmere fibres length is shorter, spinning performance is poor; Its single end strength is low; Coefficient of friction is little, and cohesive force is low poor, therefore, in spinning process, especially after combing, can produce more length about 20mm and/or the cashmere staple fibre of 20mm~25mm scope.The essentially no weaving value of this part cashmere staple fibre, so, be not used further to textile clothing industry usually.
For many years, people attempt by improving spinning method, to from the cashmere spinning material of high value, comb from, its fibre length is used in the fabric spinning at the cashmere staple fibre of 20~25mm, in the hope of making full use of the cashmere spinning material of high value, but do not have effectively, the success in the practicality.
Cashmere fibres length is shorter, about 20-45mm.The fibre length of cashmere fiber that can be directly used in textile clothing usually is in the scope of 30~45mm.As the apply for a patent production method that disclose a kind of cashmere yarn of number of patent application for " 66~80 public pure high-count cashmere yarn and production method thereof " of " 92100334.X ", wherein, the intermediate length of employed raw material cashmere fiber is greater than 35mm.Again, the patent No. is " 93206404.3 " " a kind of high-elastic cashmere cladded yarn ", and number of patent application for " a kind of cashmere cladded yarn " of " 91227317.0 " though the utility model application patent refer to a kind of spandex, polyamide fibre cashmere wrap yarn, but do not refer to its raw material that uses at all, especially concrete quality, the fibre length of cashmere raw material and fail to disclose the concrete manufacture method of its cashmere wrap yarn, the cashmere wrap yarn of the above-mentioned document of this page explanation fails to break away from traditional spinning process and theory.In addition, the related cashmere yarn of above-mentioned two documents only refers to the blended yarn of cashmere and chemical fibre.
As mentioned above, by traditional spinning process, theory and practice thereof, can't with fibre length about 20mm or the cashmere staple fibre of 20~25mm effectively utilize again in spinning and the weaving of fabric.Utilize raw materials such as cashmere staple fibre as desire, spin the cashmere fiber fabric of high-grade cashmere fiber yarn and excellent performance thereof, grade elegance, and form practical suitability for industrialized production, then technological principle, operation etc. such as cashmere spinning must be done bigger reform.
Being the application's applicant and inventor, application on January 7th, 1999, number of patent application one of its main inventor is the applying for a patent in the specification of " super short fiber yarn, its fabric and the preparation method " of " 99113405.2 ", has disclosed a kind of cashmere super short fiber yarn, its fabric and preparation method.But, fleece fabrics and manufacture method thereof that the specification of this application only discloses a kind of cashmere super short fiber yarn of mainly being made up of at the cashmere superbhort fiber of 20mm and following scope thereof fibre length, made with this cashmere super short fiber yarn, and to fibre length in the utilization of the cashmere short fibre yarn of 20~25mm scope, spin and do not make an explanation.Secondly, this application document is put down in writing, fibre length is in the principal character of the manufacture method of the cashmere super short fiber yarn of 20mm and following scope thereof: long fibers such as low-melting vinylon are spun into the yarn nexine as resultant yarn with functional long fiber, its peripheral entanglement has after dystectic cashmere superbhort fiber, this yarn is spun into fabric, then, be higher than long stapled low melting point, be lower than under the high melting temperature of cashmere fiber with organic acid, carry out acid dip and handle, low-melting synthetic continuous fibre in the above-mentioned fabrics is removed in dissolving; Thus, form the pure fleece fabrics that the cashmere super short fiber yarn only be made of the cashmere superbhort fiber makes; In addition, the document does not relate to fully yet utilizes the cashmere long fiber as the functional long fiber of resultant yarn, spins the method for pure cashmere short fibre yarn.
In practical operation, the application/inventor finds that there are certain problem in above-mentioned cashmere super short fiber yarn, fabric and manufacture method thereof:
In the organic acid impregnation process process that the low melting point long fiber is done, desire to remove fully the synthetic continuous fibre that is arranged in fabric, yarn core (nexine), required pickling intensity, time are wayward;
Pickling handle as control improper, easily stay the vinylon long fiber of the fusion of not removing fully, cashmere fiber and fabric quality thereof, outward appearance are caused and seriously influence;
Described low melting point synthetic continuous fibre only limits to vinylon fiber at present;
Low melting point vinylon fiber price is bigger, is difficult for buying.
In addition, even do not adopt pickling to handle, directly form the cashmere blended yarn of the synthetic fiber such as cashmere/vinylon of its peripheral entanglement cashmere superbhort fiber, because of its cashmere fiber length too short, can't successfully spin the blended yarn of cashmere/synthetic fiber with certain intensity, excellent quality, or the like.
In view of above-mentioned, the present inventor is after the research to the organic acid impregnation process of the cashmere superbhort fiber of fibre length below 20mm, again fibre length is studied at the spinning method of the cashmere staple fibre of 20~25mm, find: with part long fiber (30~55mm), particularly utilize long (30~45mm) the cashmere long fiber of fibre length, used as the functional long fiber of the resultant yarn that mainly is positioned at the yarn nexine, fibre length is used as the main fibre that mainly is positioned at external layer of yarn at the cashmere staple fibre of 20~25mm; Under the open-end-spinning condition, cashmere blend fibre yarn or the pure cashmere fiber yarn of be spun into nexine long fiber/outer staple fibre, mainly forming at the cashmere staple fibre of 20~25mm by fibre length.Again by the above-mentioned cashmere short fibre yarn that makes, can make the blended cashmere fabric of mainly forming at the cashmere staple fibre of 20~25mm simultaneously by fibre length, perhaps, particularly, make the pure cashmere fiber fabric of mainly forming at the cashmere staple fibre of 20~25mm scope by fibre length.
